Working with ESP8266 (ESP-07S)

I have noticed this version of the ESP8266 features an IPEX connector for an antenna. I was wondering if it differs in any other ways from other chips and if there are any issues with it or anything else I should know?

Should be the same ESP8266EX chip in all of the ESP-xxx modules.
Some are configured with more flash memory.
Some expose additional pins.
Some have a metal can / shielding.
See http://esp8266.net/ for more specifics.

IPEX / U.FL connectors are only rated for a small number of reconnects. Maybe 20-30x reconnections. That's the main concern.
They are also 50 ohms impedance, as with bigger (RP-)SMA connectors.
Short U.FL -> SMA pigtails are fairly common and cheap.
